He was the main investigator in both Mitchell Reports.
On August 10, 2007, ABC News reported that Senator Mitchell had been diagnosed with prostate cancer.
In 1974 he won the Democratic nomination for governor of Maine, defeating Joseph Brennan. Mitchell lost in the general election to independent candidate James B. Longley, but was appointed United States Attorney for Maine by President Jimmy Carter in 1977. Mitchell served in that capacity from 1977 to 1979 when he was appointed to the United States District Court for the District of Maine. Mitchell served as a federal judge until he was appointed to the United States Senate in May 1980 by the governor of Maine, Joseph Brennan, when Edmund Muskie resigned to become U.S. Secretary of State.
He was elected to a full term in 1982, reelected in 1988 and did not run for reelection in 1994. He rose quickly in the Senate Democratic leadership, serving as Deputy President pro tempore from 1987 to 1988. He then served as Senate Majority Leader from 1989 to 1995. In 1994, President Bill Clinton offered him a seat on the Supreme Court. He declined, citing his desire to focus on the health care plan that was then before the Senate.

Since 1995, he has been active in the Northern Ireland peace process as U.S. Special Envoy to Northern Ireland. Mitchell first led a commission that established the principles on non-violence to which all parties in Northern Ireland had to adhere and subsequently chaired the all-party peace negotiations, which led to the Belfast Peace Agreement signed on Good Friday 1998 (known since as the Good Friday Agreement). Mitchell's personal intervention with the parties was crucial to the success of the talks. He was succeeded as special envoy by Richard Haass. For his involvement in the Northern Ireland peace negotiations, Mitchell was awarded the Presidential Medal of Freedom (on March 17, 1999) and the Liberty Medal (on July 4, 1998).
In 2000 Al Gore reportedly consider naming Mitchell his running-mate. Gore, however, ultimately selected Joe Lieberman. Had Mitchell been nominated and the Democratic ticket won that year, he would have been the first Arab American to serve as the Vice President of the United States and just the second Vice President from Maine after Hannibal Hamlin.
Since 2002, Mitchell has been a Senior Fellow and Senior Research Scholar at the Columbia University Center for International Conflict Resolution, where he works to help end or avert conflicts between nations.
He has frequently been mentioned in the past in conjunction with potential appointment for the position of Commissioner of Baseball, but nothing to accomplish this has ever been effected. He also has been mentioned in both 2000 and in 2004 as a potential Secretary of State for a Democratic administration, due to his role as Senate Leader and the Good Friday agreements.
He is the Chancellor of the Queen's University of Belfast, Northern Ireland, and namesake of the George J. Mitchell Scholarship, which sponsors graduate study for twelve Americans each year in the Republic of Ireland and Northern Ireland.
He is the founder of the Mitchell Institute, in Portland, Maine, whose mission is to increase the likelihood that young people from every community in Maine will aspire to, pursue and achieve a college education.
He is Partner and Chairman of the Global Board of DLA Piper, US LLP, a global law firm.
On March 4, 2004, Disney's board of directors, on which he had served since 1995, named him Michael Eisner's replacement as Chairman of the Board after 43% of the company's shares were voted against Eisner's reelection. Mitchell himself received a 25% negative vote, a fact that led dissident Disney shareholders Roy E. Disney and Stanley Gold to criticize the appointment of Mitchell, whom they saw as Eisner's puppet. On June 28, 2006, Disney announced that its board had elected one of its members, John Pepper, Jr., former CEO of Procter and Gamble, to replace Mitchell as chairman effective January 1, 2007.
Mitchell spent time as a Director in the front office for the Boston Red Sox, but quit on November 15, 2006.
He served as co-chairman (with Newt Gingrich) of the Congressionally mandated Task Force on the United Nations, which released its findings and recommendations on June 15, 2005.
In 2007, he became a visiting Professor in Leeds Metropolitan University's School of Applied Global Ethics and the University is developing a new Centre for Peace and Conflict Resolution bearing his name.
Mitchell released a 409-page report of his findings on December 13, 2007. The report includes the names of 89 former and current players for whom it claims evidence of use of steroids or other prohibited substances exists. This list includes names of Most Valuable Players and All-Stars, such as Roger Clemens, Andy Pettitte, Miguel Tejada, Denny Neagle, Paul Lo Duca, David Justice, Barry Bonds, Eric Gagné, Todd Hundley, Randy Velarde, and Benito Santiago.
Mitchell has taken on a role similar to that of John M. Dowd, who investigated Pete Rose's gambling in 1989.
Interestingly, Mitchell, a Director for the Boston Red Sox, accused more players from the rival New York Yankees of using steroids than from any other team. This raised serious questions among many experts and baseball fans over the impartiality of the report, given Mitchell's former connections to the Red Sox.
